Specification of Letters Patent.

rratentea Maren 26, 1907.

Application filed December 17, 1906. Serial No. 348,219.

To @ZZ whom it may concern:

Be it known that I, CLARENCE H. HOW- ARD, a citizen ofthe United States, residing at St. Louis, in the State of Missouri, have invented a new and u eful Improvement in Locomotive-Tender and Tank-Car Frames, of which the following is a specification.

My invention relates to the underframe of a cylindrical longitudinally-arranged locomotive-tender or tank-car body, and has for its object to provide a strong, compact, light, and rigid structure adapted to firmly support the said body cradlewise for its entire length, with or without fastenings, and thereby revent lateral straining and lay thereof W en traveling around curves atlliigh speed.

It consists -principally in forming the top of the underframe practically for` its entire length transversely with a'curvaturecorrespending to the circumferential contour of the tender or tank-car body, combined with other features of novelty, 'as hereinafter described and claimed, reference being had t the accompanying drawings, forming partof this specification, Whereon- Figure 1 is a top plan view of lmy im roved underframe; Fig. 2, a side view t iereof, partly in elevation and partly in section on ine 2 2 in Fig. 1 g Figs. 3 and 4, cross-sections, to enlarged scale,.through the underframe on lines 3 3 and 4.4, respectively, in Fig. 1; Fig. 5, a vertical longitudinal section, to enlarged scale, through therear end portion of the underframe on line 5 5 in Fig. 1 and Fig. 6, a cross-section thereof on line 6 6 in Fig. 1.

Like letters and numerals of reference denote like parts in all the figures.

a represents my improved underframe, which 1s composed, preferably, of cast-steel integral throughout and adapted to support crad ewise in the present case a substantially cylindrical tender body l), -(shown broken away by dotted lines in Fi s'. 2, 3, 4, 5, and 6,) arranged longitudinally t ereon, but may be used with slight modification of its subordinate parts as an underframe for supporting the cylindrical tank in that class of car known as a tank-car.

The underframe a is preferably rectangular-shaped in top plan view, comprising two side members c, which are united to each other by two end members d d and by two transverse members e e intermediate to the 4part of the outer cylindrical surface of the tender-body b, which bears thereon practically for the entire len th of the underframe a and on the similar -curved top of the transverse members or body-bolsters e e', re-

spectively, whereby the under part of the tender-'body b is bedded in the curvature of the underframe a and lateral strain on the tender-body b when rounding a curve resisted thereby. i

In the'front end member d of the underframe a, midway between the side members c, is formed the pocket 3 for receiving the end of the bar or link by which the underframe a is coupled to the locomotive, the pocket 3 being perforated vertically for the passage therethrough of the cou 'ling pin, (not shown,) while at the top an in front of the end member d is formed the outwardlyprojecting pocket 4 for receiving the buiiingsprings, (not shown,) thepocket 4 being united to the body of the end member d by preferably a hollow reinforcing-piece immediately over the pocket 3, combined with strengthening-ribs 6, suitably arranged about the said parts to form a strong and rigid construction thereat integralthrou hout.

The rear end member d o the underframe a consists in thepresent case of a longitudinally arranged inverted U shaped channel-piece 7, located midway between the side members c and having the bottom edges, of its side walls and o ening thereat flush, or thereabout, with thel ower flanges 2 of theside members c, the U-shaped piece 7 being united externally to the webs4 1 of the side members vc by a series of vertical parallel webs 8 ,arranged transversely thereto, combined with a horizontal web 9, intersectin the webs 8, the whole forming a strong an rigid end to the underframeaI for resisting shocks from collision.'

The transverse member or body-bolster e adjacent to the rear end member d is in the present case preferably adapted for the ap- IOC ` body-bolster e', as

used) are cast on the inner faces o vpockets 3 and 4, as above -able draft-gear plication thereto of a suitable Adraftear, such as that for which Letters Patent o the United States weregranted to Harry M Pfia er January 23, 1906, No. 810,805, in whic the usual nated, as indicated by dotted lines in Fig. 5, in which case the draw-bar extension 11 is inclined u ward from its inner end adjacent to the bo y-bolster e and passes at its outer end ortion with the draw-bar 12 throufgh the channel of the U shaped iece 7, or, if esired, in lieu of applying the draft-gear to the shown and described, a suitable .draft-gear may be applied directly to the end member d', in which case -vertical lugs or stops 13 for the followerlates (if the side walls of the U-sha led channel-piece 7, as indicated by dotte lines in Figs. 5 and 6. Furthermore, in the case of a tank-car the front end member d in lieu of having the described, may be constructed similarly to the rear end member d and the body bolster e adjacent thereto adapted for the application of suitthereto -or not, as in the case of the body-bolster e It is here noted that although the underframe a is above described as preferably integral throughout it maybe made 1n two parts respectively integral and secured to# follower-plates are e l1m1' gether preferably midway of the Qf otherwise, as found most suitable.

`What I claim as my invention, to` secure by Letters Patent, is` i The combination with a cylindrical locomotive-tender or tank-car body, of a castmetal underframe, comprising, two longitudinal side members, two transverse end members, and two transverse members intermediate to the end members and adapted to form the'body-bolsters of the said frame, the said side and intermediate members beingconformable at the top to the outer cylindrical surface of the said body and adapted thereat to support the same, one of the said intermediate members being adapted for a plying a suitable draft-gear thereto, and t e adjacent said end mem er having a channel and desire theframe by flanges 14: and rivets 15, as indi-1 1 catedv by'dotted lines in Figsfl and 4,

in its under side for the passage therethrough of the draw-bar, and a series of webs uniting the Walls of the said channel to the said side members, substantially as described.

In' testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CLARENCE H. HOWARD.
